(1) The contingent consideration was recognized as part of the 2021 Shareablee acquisition. In April 2022, the contingency was resolved and the full amount was deemed payable. Refer to Footnote 2, Summary of Significant Accounting Policies. In December 2024, the Company elected to settle the third and final installment in cash, which was paid in the first quarter of 2025. The fair value of this liability as of December 31, 2024 was equal to the payment due. The contingent consideration liability was classified within other current liabilities in the Consolidated Balance Sheets as of December 31, 2024. There were no changes to the Company's valuation techniques or methodologies during the year ended December 31, 2024.

Fair Value Measurements on a Nonrecurring Basis
For the year ended December 31, 2025, the Company recorded the initial fair value of Preferred Stock, net of issuance costs, of $89.7 million within mezzanine equity. Refer to Footnote 4, Convertible Redeemable Preferred Stock and Stockholders' Equity (Deficit), for further details. The initial measurement of the Preferred Stock is classified as a non-recurring Level 3 fair value assessment due to the significance of unobservable inputs developed in the determination of the fair value. The Company used a binomial lattice model to determine the fair value of the Preferred Stock at the Closing Date. The Company used significant inputs and assumptions which included the price and expected volatility of the Common Stock, risk-adjusted discount rate, risk-free-rate and expected term as of the Closing Date. The initial fair value of the Exchange Common Stock was $66.6 million, of which the Company recorded the par value of $9.9 thousand within permanent equity and the remaining $65.5 million within additional paid-in capital, net of the issuance costs. The initial measurement of the Exchange Common Stock is classified as a non-recurring Level 1 fair value assessment as the Company used the closing market price of Common Stock to determine the fair value on the Closing Date. For the year ended December 31, 2024, the Company recorded the additional shares of Series B Preferred Stock of $19.6 million within mezzanine equity and $13.0 million within additional paid-in capital, which was based on the calculated fair value net of issuance costs. Refer to Footnote 4, Convertible Redeemable Preferred Stock and Stockholders' Equity (Deficit), for further details. The initial measurement of the additional shares of Series B Preferred Stock was classified as a non-recurring Level 3 fair value assessment due to the significance of unobservable inputs developed in the determination of the fair value. The Company used a binomial lattice model to determine the fair value of the additional Series B Preferred Stock at the 2024 Issuance Date. The Company used significant inputs and assumptions which included the price and expected volatility of the Common Stock, risk-adjusted discount rate, risk-free rate, expected term, deferred dividends and the timing and probability of a special dividend being called and paid as of the 2024 Issuance Date. For the years ended December 31, 2024 and 2023, the Company recorded goodwill impairment charges of $63.0 million and $78.2 million, respectively. Refer to Footnote 9, Goodwill and Intangible Assets, for further details. The remeasurement of goodwill is classified as a non-recurring Level 3 fair value assessment due to the significance of unobservable inputs developed in the determination of the fair value. The Company used a discounted cash flow model to determine the estimated fair value of the reporting unit. The Company made estimates and assumptions regarding future cash flows, discount rates, long-term growth rates and market values to determine the reporting unit's estimated fair value. It is possible that future changes in such circumstances, or in the variables associated with the judgments, assumptions and estimates used in assessing the fair value of the reporting unit, would require the Company to record additional non-cash impairment charges. About Fair Value Disclosures
Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.
Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
